Getting started

AVAsynchronousKeyValueLoading

asset.rx.playable.subscribe(
  onSuccess: { playable in
    // Do something nice.
  }
)

KVO

player.rx.status.filter { $0 == .readyToPlay }.subscribe(onNext: { _ in
  player.play()
}).addDisposableTo(self.disposeBag)

playerLayer.rx.readyForDisplay.filter { $0 == true }.subscribe(onNext: { [weak self] _ in
  playerLayer.frame = self?.videoView.bounds
  self?.videoView.layer.addSublayer(playerLayer)
}).addDisposableTo(self.disposeBag)

Notification

item.rx.didPlayToEnd.subscribe(onNext: { _ in
  player.seek(to: kCMTimeZero)
  player.play()
}).addDisposableTo(self.disposeBag)
